Modelling square/rectangular bund fires in Shell FRED HCM software

[fredhazard]

Does anyone have experience using Shell FRED to map radiant heat curves for a rectangular or square bund fire? The pool fire scenario only allows circular fires and the trench fire only allows rectangular fires with greater than 2:1 aspect ratio. Any suggestions?

Hi Fred,

I don't have specific experience with FRED, however, there is an article about large pool fire with the conversion from rectangular or square to circle.
Attached is the article, please refer to Problem 2 for the methodology.

Hope this will help you

Thanks pwijaya - seems like a reasonable way to approximate a non-circular pool fire. I had hoped there would be some way the software could model specific bund shapes but it seems like that isn't possible.
